Answer and Explanation:
Artists' lives have been changed by digital technology. This has created different schools of thought such as the "winner take all" theory, which claims that delivering high quality products at low cost will create a world where small differences in talent demand large differences in reward, and the "long tail" theory, who claims that digital technology is creating a small portion of sellers that the market will adapt to, promoting low-cost products. These two theories are effective in different realities. However, the existence of both proves the change that programming and technology has been showing in entertainment and in the market.
Answer:
14.34%
Explanation:
To find the percentage of returned surveys over the total we divide and then multiply:
(717/5000)*100= 14.34%
The response rate appears to be low because it is less than 50% (which would be 2500 return surveys). Some statistical studies agree that 30 is the minimum number of observations a study must have, but this number does not ensure statistically significant results.
The problem with a very low response rate is that survey´s answers does not significant represent the study population characteristics and so we cannot make inferences, correlations or regressions that are statistically significant. In this case, the conclusions that scientists make about association between the left-handed population and right-handed population with the use of cell phone calls could be wrong or not represent the population characteristics, which means answers are not trustful.
